I think you've got a great channel man! Your personality is very relaxing and fun to listen to (which is something that I think is slowly going away on YouTube). You look like you're having an awesome time making videos which is great for viewers to pick up on. You're making awesome videos! Giveaways are a great way to grow your channel while it's still young. Your thumbnails are very poppy and eye-catching which is great! Overall, your channel is awesome and if you keep up the consistency, I think you could go very far!
I know you're looking for some constructive feedback. If I were to suggest a couple things, I'd say that you might want to invest in a nicer microphone to really make your videos seem more professional. You've got a great voice and with a studio quality mic, you could really captivate your audience.
Also, I would suggest that you try and do some live facecam gameplays going for nuclears or other high kill gameplays! Just from what I've seen you seem life a very good player and I think people would really enjoy that!
I hope you found this feedback helpful!
